Card number recognition apparatus and card number recognition method

摘要

There is provided a card number recognition device capable of easily and accurately recognizing a card number even at a card having a pattern on the background of the card number. According to an embodiment, a card number recognition device includes a line segment group detection unit, a first character recognition unit, and a second character recognition unit. The line segment group detection unit detects a region where pixels having a first pixel value and pixels having a second pixel value appear at a predetermined ratio in the first direction for each linear region including a pixel group continuous in the first direction. Then, a predetermined number of line segments in the second direction orthogonal to the first direction are detected. The first character recognition unit sets a region for detecting a specific number based on the position of a predetermined number of line segment groups, recognizes the character, and detects a specific number in the card number. Based on the position of the specific number, the second character recognition unit sets an area for detecting a number other than the specific number located before and after the specific number, recognizes the character, and the specific number in the card number Detect numbers other than.
